1×2 Unbalanced PLC Splitter 85/15, Mini 0.9 mm SC/APC

BWN-PLC-MMST-1X2-SC-APC-0.9-U8515

Exact configuration at a glance

The proposed BWN-PLC-MMST-1X2-SC-APC-0.9-U8515 is a connectorized 1×2 single-mode PLC splitter with nominal 85% and 15% outputs. The supplied build evidence shows a 60 × 7 × 4 mm mini steel-tube package, G657A1 0.9 mm fiber, 1.0 m leads and SC/APC connectors. Use the 85% and 15% paths as two separate budget lines; do not apply an equal 1×2 loss value to this part.

Identity hold: TBC — BWNFiber must confirm that the proposed U8515 model maps to the photographed unit and test record, serial 25120100007.

Short answer for buyers

This is not a standard 50:50 splitter. Its two outputs are nominally labeled 85% and 15%, so their insertion-loss limits differ substantially. It is intended for a protected tray, terminal or closure where the mini steel tube and 0.9 mm leads fit the fiber-management plan. Before approval, confirm the physical port labels, per-path optical budget, SC/APC interfaces, test method and exact document revision.

Key features of the proposed build

• 1 input and 2 unequal outputs, nominally 85% and 15%
• Mini steel-tube package shown as 60 × 7 × 4 mm
• Single-mode G657A1 fiber shown on the supplied sheet
• 0.9 mm fiber construction with 1.0 m length shown on the supplied sheet
• SC/APC connectorized input and outputs shown in the product photographs
• 1260–1650 nm operating wavelength shown on the supplied sheet
• Separate insertion-loss limits for the 85% and 15% paths
• Per-unit readings shown at 1310, 1490 and 1550 nm for photographed serial 25120100007

Every item above remains subject to the approved model datasheet and order configuration. The photographed record is evidence for one build, not a promise that every unit shares the same measured readings.

Technical specifications

Port map and optical limits

The function names “express” and “tap” depend on the approved network design. Do not assume that the 85% tail must continue to the next cabinet or that the 15% tail must serve a local endpoint until the topology and label convention are approved.

Photographed per-unit optical readings

The supplied image shows the following values for serial 25120100007, inspected 2025/12/1. These are transcribed observations from a photographed sheet. Test method, reference method, equipment, calibration, uncertainty and release authority were not supplied.

Do not use these per-unit readings as universal typical values. Build the design and acceptance criteria from the approved maximum for each path and the project's required margin.

Interfaces and physical integration

The photographed unit has green SC/APC connectors on the input and both outputs. Confirm that every mating adapter and patch connection in the approved path also uses the specified APC interface. The mini steel tube does not replace a protective enclosure. Verify tray clearance, mounting position, fiber exits, bend control, connector access, service slack and protection for the 0.9 mm leads.

The supplied evidence does not establish an IP rating, outdoor standalone rating, jacket material, flame rating, UV resistance, tensile rating, crush rating or minimum bend radius. These fields must not be inferred from the steel tube or the G657A1 designation.

Compatibility and application conditions

Evaluate this product only where an unequal 85/15 optical-power division is part of an approved design. A possible design task is to retain the larger share on one path and send the smaller share to a second path, but the final use must be supported by a complete power budget.

Before specifying it for GPON, XGS-PON, CATV, monitoring or another system, confirm:

1. the wavelengths used by the system;
2. transmitter output and receiver operating limits for every endpoint;
3. loss from the splitter, connectors, splices and fiber route;
4. any upstream/downstream asymmetry and minimum-loss/overload condition;
5. required engineering margin and cascade stages;
6. the physical host enclosure and connector interfaces; and
7. the operator's acceptance method and document requirements.

No universal equipment-brand compatibility or transmission-distance claim is made in this draft.

How to select and approve the correct configuration

1. Confirm the ratio convention. State which physical output must carry the higher nominal share and how the two tails will be labeled.
2. Calculate both paths. Use the approved maximum for the 85% output and the approved maximum for the 15% output; include connectors, splices, route attenuation, cascade stages and margin.
3. Check the host space. Compare a controlled drawing—not only the nominal dimensions—with tray clearance, exits and bend-control parts.
4. Confirm the interfaces. Record SC/APC at every mating point and define whether any field splicing is required.
5. Approve the evidence pack. Request the current datasheet, drawing where needed, and the agreed test-report format before the purchase order.
6. Lock the order code. Match model, ratio, fiber, diameter, lengths, connectors, labels, quantity and document requirements on the quotation and PO.

Difference from adjacent BWNFiber content

Use cases and non-fit conditions

Potential fit after engineering approval

• A protected PON distribution point that requires a defined higher-power and lower-power path
• A tray, terminal or closure with confirmed space for the mini steel tube and 0.9 mm routing
• A project that specifies SC/APC and requires per-path model-level optical limits
• A procurement process that needs visible port labeling and a traceable test record

Do not specify this build when

• the design requires equal 50:50 outputs;
• the 15% path cannot meet receiver requirements after worst-case loss is calculated;
• the host has no protective enclosure or bend control;
• the mating interfaces are UPC or otherwise incompatible with the approved connector plan;
• the project requires an IP, fire, environmental or compliance rating that has not been documented for this exact model; or
• the buyer cannot obtain an approved datasheet/test record matching the order code.

Testing and quality-control information to approve

The photographed sheet includes IL, PDL and RL fields at 1310, 1490 and 1550 nm, plus directivity and temperature specifications. Before these values become release claims, the quality owner should confirm:

• the exact model and serial mapping;
• the test method and reference condition;
• whether connector loss is included;
• instrument identity, calibration status and measurement uncertainty;
• acceptance limits and disposition of failures;
• port-label traceability from sheet to physical unit; and
• whether the report is supplied per unit or per batch.

TBC — a controlled document, not the photographed image alone, should be the downloadable technical record.

Packaging and procurement information

Packaging format, dust-cap protection, individual/bulk packing, label content, MOQ, price, stock, lead time, warranty and export-document availability are TBC — source required. Do not copy these fields from another ratio, product family or current blog page.

Information required for an RFQ

Send:

• product request: 1×2 unbalanced PLC splitter;
• nominal ratio and convention: 85% / 15%, including which labeled tail serves each route;
• fiber grade, diameter and input/output length;
• connector and polish on all three ends;
• host tray, terminal or enclosure model/drawing;
• maximum allowable loss for each path and required wavelengths;
• required test report, drawing, compliance or inspection documents;
• quantity, destination and target schedule; and
• BOM, topology or PON power-budget worksheet when available.

BWNFiber should respond with the approved model code, configuration confirmation, model-specific data/document list, quotation and lead time. This response commitment must be confirmed by Sales before publication.
